MOUNTING OF PULLEYS EMPLGYE'D IN THE TAPE DRIVING OF SIINDLES IN RING PAWTUCKE'I, RHODE ISLAND.

SPINNING AND DOUBLING- FRAMES. I

Application filed December To all whom it may concern Be it known that I, WILLIA ARTHUR VVALSII, a subject of the King of Great Britain, residing at Accrington, Lancashn'e, England, have invented certain new and useful in'iprovements in and relating to the mounting of pulleys employed in the tape driving of spindles in ring spinning and doubling); frames, of which the following is a specification.

The invention relates to the pulleys employed in the tape driving of spindles in ring spinning and doubling. frames, and ln which frames it is requisite to provide means whereby spindles may be driven weft way or, alternatively, twist way at will, as is understood, or vice versa. 7 1

The object of the invention is to provide a series of mounts or supports in pairs, or one pair for each pulley-carrier, and so that the transference of each pulley-carrier from one support to another of a pair, will at once result in change of angular position of the In one form of support eachis formed with projecting jaw-cavities or bearings beyond the axis of the shaft or mount referrcd to, the lower end of one cavity or hearing}; beingslightly nearer (according to the required conditions) the axis of said shaft than the lower end of the other cavity or bearing for the same support, the cavities or hearing named being on opposite sides of the support. This means, for the purpose of conforming to the conditions whereby change from weft-way to twist-way driving of the spindles may be attained, or viceversa, the position of the axis or pivot of the pulley-carrier relatively to the axis of the shaft or mount. is different, both as re gards component horizontal and vertical Certain parts of the latter and of the been manipulated suitably \Vith reference to said drawings Fig. 1 is invention. Said Fig. 1 is on a reduced scale relatively to the remaining figures of the drawings.

Fig}. 2 shows a side view also of the sup" port in Fig.1 with details added to. make the invention clear. i

Fig. 3 is a view at right angles to Fig. 2

andwith a. part ot a pulley-carrier included.

support are'sectioned; I

F ig. 3 aforesaid indicates a support arranged to be suitable for the pulley-carrier mounted thereinwhen the spindles are being driven weft way,- the view shown being assumed to face said spindles. That is to say, in 1 spindles are assumed to be to the right of the carrier-indicated, and the tin roller t0 the left.

F 4 is a similar view to Fig. 3 excepting that the conditions are suitable for the spindles being driven twist way. The supports in Figs. 3 and 4 thus form a pair situated at a suitable distance apart on the shaft shown, the pulley-carrier being capable of being moved from the one to the other so as to take up the positions illustrated, but alternatively as desired. v

. Fig.5 shows a modification of the invention rc'latively to Fig. 3, but the alteration necessary for it to form a modification of Fig. 4 is obvious.

a is a pulley for guiding its tape from the tin roller to the spindles, or may be pairs of spindles on each side of the tin ,ro ler in the case of a double frame.

b is the pulley-carrier, the lower end of which is formed with a counterbalance weight (not shown). An extension or bar 0 from b, may be employed and suitably weighted when employed in twisting frames, or may be ring spinning rames. i

d is a shaft parallel to the axis of the th roller, not indicated, and here mounted fixedly upon a bracket 6 attached to a part it of the framing of the machine.

' In Figs. 1 to 4 inclusive, the pulley-carrier b is provided. With projecting pins 7;

whereby the carrier may be pivoted within the support k formed with jaws Z for the purpose. The supports illustrated are shown capable of attachment to shaft (Z by means of set-screws.

In Fig. 2 a pin 2' on one side of the support is shown in section, and a similar pin on the opposite side of the support is merely indicatcd by means of a. circle for clearness. As already described, the direct distance between the centre of the sectioned pin and the centre of shaft (Z in Fig. 2 is different to the direct distance between the centre of the pin end shewn plain and said shaft axis; so that the plain pin end is not only farther to the right (or more advanced) than the sectioned pin end, but is also at a different elevation, the two directions being components of a direct distance above referred to.

In this way, on account of the cavities or jaws of the support being arranged to bring about the above result, the pulley a is given the requisite tilts in the horizontal and vertical planes.

In the figures shown, the supports are formed with upper extensions, terminating in each case with a face or surface on. whereby the possible movement of the pulley-carrier b or pulley a towards the tin roller may be limited.

In Fig. 5 the pulley-carrier b is formed with side hearings or yokes a capable of resting upon angled side pins 0 projecting from the support is. are not necessary, and it is obvious that the yokes a may be extended downwards to a greater length than shown.- It will be seen that between the side parts or jaws in the iarious figures, there is space allowed totake the pulley-carrier b in each instance, that is to say, the surface of the support behind said carrier may be approximately in the same vertical plane as the surface m in Fig. 2 or otherwise.

it will thus be seen that by providing a pair of brackets for one pulley-carrier, mounted upon a shaft or equivalent, each bracket formed with angular parts so that the engagement of the pulley-carrier therewith, results in the necessary tilting of the latter, the tilting for the one bracket of a pair being suitable for wef way driving of the spindles, and the tilting for the other In this example jaws bracket of a pair being suitable for twist way driving of said spindles, said pulleycarrier only requires to be bodily moved from one bracket of a pair to the other of said pair to bring about the change of angular position referred to.

Of the supports forming a pair in Figs. 3 and l, the one is herein referred to as of opposite hand" to the other.

1. For the mounting of pulleys employed in the tape driving of spindles in ring spinning and doubling frames, a weighted pulley-carrier freely supported at each side upon inclined mounts forming part of said support, one of said mounts situated in advance of the other, and said support adapted for fixation parallel or thereabouts to the axis of the tin roller of the frame, adjacent to a like provided support of opposite hand, for the purpose and substantially as herein set forth.

2. For the mounting of pulleys employed in the tape driving of spindles in ring spin- Ring and doubling frames, a weighted pulley-carrier freely supported at each side by projecting parts, inclined jaws forming part of a bracket constituting said support and for receiving said projecting parts, one of said jaws situated in advance of the other, and. said bracket adapted for fixation pirallel or thereabouts to the axis of the tin roller ofthe frame, adjacent to a like provided bracket of opposite hand, for the purpose and substantially as herein set forth.

3. For the mounting of pulleys employed in the tape driving of spindles in ring spinning and doubling frames, a weighted pulley-carrier freely supported at each side by projecting yokes, inclined pins forming part of a bracket constituting said support and for receiving said projecting yokes, one of said inclined pins situated in advance of the other, and said bracket adapted for fixation parallel or thereabouts to the axis of the tin roller of the frame, adjacent to a like provided bracket of opposite hand, for the purpose. and substantially as herein set forth.

In testimony whereof I have aflixed my signature.
